摘要
通过薄片的观察鉴定,样品的扫描电镜测试分析,并结合一些测井资料及常规的实验分析,对鄂尔多斯盆地富县探区延长组长8段砂岩的碳酸盐胶结特征进行研究,合理解释碳酸盐胶结物在砂岩的分布规律以及在成岩阶段中的作用,为寻找低孔低渗砂岩中的有利储层及后续油气开发提供重要依据。
By observation of the sheet,SEM analysis of the samples,combined with some logging data and conventional experimental analysis,carbonate cement characteristics of Chang 8 sandstones of Yanchang formation in Fuxian area of Ordos basin were studied,the distribution rule of carbonate cements in sandstone and the role of carbonate cements in diagenetic stage were analyzed,which can provide an important basis for seeking favorable reservoirs from low porosity and low permeability sandstone.
